Also, someone please check my math for mistakes!

It’s completely off! Never seen such shoddy work in my life!

On a serious note, the holiday point is an interesting one (as is your post as such!) I would add – to the pure percentages, so to speak – that it’s a bit dangerous to operate with "close to" when looking for patterns. Why would a killer choose to strike on a holiday? Well, there could be many reasons for that – but the bare fact of it makes some sense in itself. It’s a holiday, a significant stand-out date in itself. To do something significant on a significant date makes sense. To do something on a date close to (a couple of days? five? ten? where does one draw the line?) a significant one is a very different matter. It requires a different kind of explanation. *

* This as a general remark – it doesn’t pertain to KQ per se. In fact, the holiday angle seems superfluous enough in KQ’s case, since the dates in question would have been significant to him anyway, regardless of holidays.

no grand jury indictmnent with evidence of this nature..its just not goin to happen ..that being said this dates of importance is interesting and my take is it is worthy of a good look see..but the maths wizard here laid it all to waste..that is nothing to get too worked up over..all our present POI’s suffer near the top in need of "beyond a shadow of a doubt"..heck my gut is X and TK are worthy POI’s and do deserve scrutiny..mike has done a hell of a job on this..guess my question is what the hell are we missing with X that is right our in the open but we fail to see it..i dunno may be an employee know something but his brakes failed one day and he went off the cliff

But let’s look at it this way: There were only four Zodiac murder dates.

How do we know that for certain?

KQ only had two parents and one date matches each. (There were only three "parent dates" in 1968-9, since KQ’s father was still alive.) We won’t even get into the possible Freudian significance of killing on dates related to your parents.

This is an artificial significance if you can’t show the dates aren’t simply coincidental.

And there are other dates, like June 26th and November 20th, that relate to a letter and an interesting article related to the Z case.

So, even if we presume only 4 murder dates, the list of Z correspondence dates is quite extensive, greatly improving the chance of matching random events in KQ’s life.

And let me say this about July 4-5. Let’s say that you found a suspect who was born on the 4th of July and married on December 25th. If you dared to say that he matches Z dates because Z said something about Christmas and the 4th of July, people here would shout you down as being full of BS because Z actually killed on December 20th and July 5th. So you can’t win. I stand by the fact that whatever he said about July 4th, Z waited until July 5th to pull the trigger and that date matches KQ’s UFO sighting. December 20th is an exact match.

It’s not enough to "dare to say" there is a pattern to the dates. You have to demonstrate that it isn’t just happening by chance, either by showing how difficult it would be for the dates to match in the first place, or by showing some other direct evidence that it was designed by the suspect. Otherwise, there are multiple plausible explanations.

That is still only a fraction of my evidence. There is even more date related evidence.

I’d be interested in hearing more about that. Date-related patterns have come up before (example). They are fun to explore but I’m not yet aware of any discoveries that escape the shadow of coincidence, except perhaps for the crimes occurring primarily on weekends.

My curiosity can’t resist figuring out the odds of random dates falling on weekends, so here goes. Let’s say Fri, Sat and Sun are included in our "weekend" definition, and there are 52 of each in any given year. So the chance of one random date falling on a weekend is (52+52+52)/365 = 43%. If we say that Zodiac has exactly 4 murder dates, then the odds that all 4 happen fall on a weekend by chance are: 43% * 43% * 43% * 43% = About 3%.

z operated during the weekend. any significance of dates beyond that takes second fiddle to the fact that z operated during the weekend.

Yeah – and that in itself, i.e. that he operated on weekends, makes sense. It fits the bill, so to speak. In establishing a pattern it’s important that said pattern seems intuitively…right. Which the weekend thing does, to the point where one can say that the alternative, viz. that these dates are all random (he could just as well have struck on a Tuesday, two Wednesdays and a Thursday) seems less likely.

If I, for instance, theorize that Z was a 9-4 guy who didn’t have time to cruise for victoms during the week, then this seems to have some merit based on the facts.

Did X have a nickname that you know of Mike?

Hi-

Someone told me once that he had a nickname but this was an anonymous source whose credibility for the amazing things he told me I could not establish. If you know what the nickname was and are correct, it would give me great hope that this source, who has disappeared under the billowy waves since 2007, wasn’t full of sh*t. You can send me a PM if you know it.

Mike

sorry Mike..i do not know..id be very interested in knowing if credibilty can be verified from a 100% reliable source

Hi-

If I tell anyone, I can’t use it down the road to verify this source’s credibility. So for now I have to keep it to myself. ;(

Mike

Mike have you looked thru advertising media put in the paper, magazines by X’s dealerships..if so anything of interest found Z related

No. I’ve never tried to round up all the ads he might have taken out. That calls for knowing in which publications and when he may have advertised.

Mike

do any pictures of Mr Y (brother of Mr X) exists circa 1965 on ward???

do any pictures of Mr Y (brother of Mr X) exists circa 1965 on ward???

Which brother is Mr.Y? Weren’t there 3 brothers of Mr.X?

the brother with the first letter of "K"..but any pictures of the either brother would be fine
